Respuesta :

1.
a. Speed = distance/time
b. 1500/300 = 5m/s
c. 10 - 2 = 8/2.4 = 3.33 seconds

2.
a. 0.46 x 2.4 = 1.104 metres
b. 78.4/8 = 9.8 m/2²

Answer:

(1) a) S=D/T

b)5m/s

c)3.33s

(2) a) 1.104m

Explanation:

(1) b) S=D/T

 S=1500/300

 S=5m/s

c) T= V-U/a

 v=10

 u= 2

 a= 2.4

10-2=8/2.4=3.33s

(2) a) d=s×t

 0.46×2.4=1.104m
